A 60 year-old patient HA, who was bedridden for a few days, feels dizzy and experiences significant increase in his heart rate after standing up. If this patient is regularly taking Angiotensin Converting Enzyme (ACE) inhibitor, such as lisinopril, how will this drug affect his sympathetic discharge to the heart, to veins and to arterioles? What changes in his blood pressure can be expected? What advice should be given to this patient?

87. A 58-year-old man who is a construction worker comes to the office because of a 1-week history of pain on the right side of his head. One week ago, he says he struck his head on a beam while carrying drywall to the second floor of a house under construction. He has had dry mouth, excessive thirst, and increased urinary frequency during this period. His pulse is 120 /min, respirations are 25/min, and blood pressure is 120/65 mm Hg. Physical examination shows dry mouth and decreased skin turgor. Urine osmolality is 196 mOsmol/kg HD (1287), An MRI c the brain shows a hyperintense signal consistent with hemorrhage of the posterior pituitary gland.

Sue goes to the gym and after an initial warm-up, she increases her exercise level pushing herself to maximum. At this point her heart rate is 175 beats/min and her stroke volume is 135 ml/beat. What is her cardiac output now? At this point, by how many ml/min has her CO increased over her resting CO? What % increase over resting is this? (Use the following equation). amount of increase in CO in ml/min % increase = _____________ X 100% original CO (resting) ml/min What term is used to describe this increase in CO?

Background 1: A patient you are seeing has blood in their sputum, Low blood pressure (hypotension) and elevated heart rate. This stems from a condition called mitral regurgitation (sometimes called mitral insufficiency). 4: Further evaluating the patient, you notice some blood work has come back. Everything there looks normal except for something called ANP- atrial natriuretic peptide. It is elevated. Why would ANP be elevated in this patient?
For each of the following situations, describe the anticipated effect on blood pressure and the physiological basis of the response: (1) a high salt diet, (2) a blow on the head that damages the vasomotor center, (3) an attack by a stalker, and (4) a hypothalamic tumor resulting in excess ADH production.
